EFFECT FOR A SINGLE ROUGHNESS E = 9,11mm OF EXPERIMENTAL TO STUDY HYDRAULIC JUMP PROFILE IN A CHANNEL IN U A ROUGH BOTTOMKeywords: Hydraulic jump , channal-shaped in U , stilling basin , channel bottom rough. Abstract: This study aims to study the hydraulic jump controlled by threshold, moving in a channel profile 'U' bottomed rough for a single roughness ε = 9,11mm. Functional relations in dimensionless terms, linking the different characteristics of the projection, showing the effect of roughness of the bottom of the channel are obtained.
